When you run an Internet-Cafe or in a public place, you want to restrict permissions to an user, if you’re the system administrator. You may want to allow only specific programs/software/applications to run on your PC. Today, I will show you how to block an application or program from running on your Windows 7 PC. This way you’ll restrict users from deleting or corrupting a particular software or program.

The instructions are as follows.

  • You need to have Administrative privileges to do this process.
  • Look for the app or program, which you want to block,  in your “c:Program Files” or where ever your Programs are installed.
  • Select the .exe file of the program and right click and select Properties.
  • Goto the Security tab and select Edit button.


Now the following Permissions window will open.

RECOMMENDED : Updating drivers manually isn’t the most efficient way to fix BSoD errors, therefore we advise you to try this Driver Update software that downloads all the necessary drivers with just one click.

Outdated drivers can often cause crashes, file loss and even permanent damage to your computer. Driver Booster quickly and automatically downloads all the drivers that you need:

1. Download Driver Booster (100% safe download and endorsed by us).
2. Once the download is complete start Driver Booster.
3. Click the Start Scan button and let the tool download all the necessary drivers.


Select the appropriate user to block access to the application/software/program. Now under Permissions for Users, click the check boxes under Deny column. Now click Apply. Then there will be a warning window, that “deny” actions will prevail over “allow” actions. Click on OK. Click on OK for the remaining windows and close them.
